Eaton WPL Spin-On Filters Ensure Hydraulic System Cleanliness

May 16, 2024
The WPL filter material features a fineness of 10 µm to prevent contaminants from entering hydraulic systems.

The WPL line of spin-on filters from Eaton’s Filtration Division are designed to protect pumps, valves, and other components within a hydraulic system from contaminants.

Key features of the spin-on hydraulic filters include:

  • compatibility with various mediums
  • flow rates up to 48 gpm (180 lpm)
  • operating pressure of 145 psi (10 bar)
  • five element sizes to meet various customer requirements.

Spin-On Hydraulic Filters Prevent Contamination 

Keeping hydraulic systems clean is vital to ensuring their performance. Therefore, when Eaton developed the WPL spin-on filters it did so ensuring they would protect hydraulic components from contamination per ISO 2941, ISO 3723, and ISO 2942 standards.

According to the company, the filters provide one of the highest cleanliness levels for hydraulic systems used in a range of heavy-duty applications including power generation, oil & gas, construction, forestry, mining and material handling. 

The WPL line of filters feature catridges designed to fit into many of the filter systems available on the market, providing flexibility for various customer applications. Five element sizes are available to meet specific customer service-life requirements. 

Each spin-on filter is comprised of a head mounted directly in-line with the piping and a cartridge containing a WP filter element. The cartridge seals to the head to prevent leakage. And because it is a spin-on design — simply requiring the filter be screwed on and unscrewed — the WPL is an easy to install and maintain filtration option as no special equipment or tooling is required as well as no emptying or cleaning of the filter. 

Filter materials are available in fiberglass or paper with a fineness of 10 µm to ensure the highest level of cleanliness possible. Eaton says the WPL filters can be used with a wide array of mediums including oils, fuels, emulsions, glycol water and synthetic fluids, aiding its use in various types of hydraulic systems.

The filters work in operating temperatures from 14-230 F (-10 to 110 C) while flow rates up to 48 gpm (180 lpm) are possible and pressures of 145 psi (10 bar), which again ensures their use in a range of heavy-duty hydraulic applications.
